UNITED STATES PATENT OFFICE.

IVILLIAM GOLDIE, OF IVILKINSBURG, PENNSYLVANIA.

METAL HOOP.

SPECIFICATION forming part of Letters Patent No. 630,603, dated August 8, 1899.

Application filed June 22, 1899. Serial No. 721,445. (No model.)

To all whom it may concern:

Be it known that I,WILL IAM GOLDIE, a citizen of the United States, residing at Wilkins burg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Metal Hoops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to barrel-hoops that are made of thin metal strips or bands, and pertains more particularly to certain constructions and arrangements of the web of a flanged metal hoop hereinafter set forth.

The improvement is especially adapted to be applied to metal barrel-hoops having a web portion and outwardly-extendin g stiffenlug-flanges. Hoops of the type referred to are shown in my application for Letters Patent executed by me on June 12, 1899.

The object of my present improvement is to secure added lateral strength to the hoop and also to permit it to more readily conform to the shape of the barrel on which it is driven.

In the accompanying drawings are shown hoops embodying my invention.

Figure 1 is a partial side View of my improved hoop. Figs. 2 and 3 are details of modified forms of my invention.

In the various views of the drawings similar figures of reference designate corresponding parts.

1 is the web and 2 and 2 are the outwardlyprojecting flanges of the hoop, formed by bending over the edges of the metal strip from which the hoop is formed.

The particular characteristics of the present improved hoop are embodied in the peculiar construction and arrangement of the web 1 relatively to the flanges 2 and 2, and consists in providing an outwardly-curved web instead of the fiat web heretofore used. This construction has important practical advantages. When the hoop is driven on the barrel, the lower edge of the hoop by reason of the outwardly-curved web readily conforms to the shape of the barrel and when fully driven holds it securely. The outwardly-bowed web gives additional lateral strength to the hoop and enables it to more efiectually resist indentation by blows received in transit and serves to reinforce the flanges 2 and 2.

The inwardly-projecting corner formed by the flange and the outwardly -bowed web serves to increase the contact-pressure and consequently the gripping power of the hoop on the barrel and to make a stronger, tighter, and safer barrel than was commonly produced by the methods of binding heretofore employed.

While I prefer in practice the curved form of web shown in Fig. 1, yet I do not desire to confine myself to this particular form, and

' consider all equivalent forms of bowed or curved websas, forillustration, those shown in Figs. 2 and 3-to be within the scope of my invention. Neither do I confine the use of this invention to barrel-hoops alone, for it is obvious that it is equally well adapted to any of the numerous uses that hoops are put to.

What I claim is 1. In a metal hoop having outwardlyflanged edges, an outwardly-curved web arranged and operating substantially as herein shown and described.

2. In a metal hoop having one or more flanged edges, an outwardly-bowed Web the body of which projects beyond the plane of the inner edges of said flanges, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM GOLDIE.
